Do you really want to use an unfinished, unstable version of ruby?

I would recommend just going with the version of Ruby Ubuntu installs  
by default and running with that for now, unless there is a specific  
reason to be running with 1.8.8 for you.

If you change line 5 of version.h from

#define RUBY\_PATCHLEVEL -1  
to  
#define RUBY\_PATCHLEVEL 1

rubygems won’t complain.
